DISPLAY-RACK WITH ADJUSTABLE ARM.

SPECIFICATION forming part of Letters Patent N0. 516,869, dated March20, 1894.

Application iiled J' une 21, 1893 Serial No. 473,321' (N0 model-l .To MZwhom t may concern:

Beit known that I, MANUEL S. MELZER, a citizen of the United States,residing in the city and countyof Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Adjustable Shelf and ShowFixture Arms, which improvement is fully set forth in the followingspecification and accompanying drawings.

My invention consists of a shelf and show xture arm which may be readilyadjusted in acute, obtuse or right angular position, or raised orlowered, or placed horizontally so as to exhibit or display goods asdesired in said positions, the bearings of the gearing for said arm, andthe arm itself being formed of sectional parts, whereby said gearing andarm may be readily removed and restored, and said bearings are attachedto a clip or clamp by which the device may be sustained in verticalposition on a standard or support and adj usted therein.

Figure 1 represents a perspective View of a shelf or show fixture armembodying my invention. Fig. 2 represents a side elevation of a portionof the same on an enlarged scale. Fig. 3 represents a top or plan viewthereof.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings: A designates a rod or standard, to which issecured the clip B, the latter being formed of sections which are hingedtogether, so as to be opened, and thus be readily applied to saidstandard, said sections having a screw O for closing the same, andfirmly clamping the clip to the standard, it being evident that saidclip is vertically adjustable on the standard, and that it may beremoved therefrom, when the screw is disconnected from one of thesections, thus permitting the latter to be opened. Projecting from theclip is an ear D, which is formed in sections, one (or both) of which ishinged as at D to the clip, whereby said sections may be opened andclosed, the pintle D2 being common to the knuckles of the clip and ofsaid ear. The ear hasa chamber E within the same at the inner endthereof, to receive the Worm F which is secured to the spindle whosebearings are on said ear. The outer end of the ear has mounted on it theWorm wheel H, which is located between the sections of the ear, and hasthe worm F meshing with it. Connected with or secured to the worm wheelis a radial arm J, which is adapted to hold goods to be displayed, orshelves, cross bars, &c., on which goods may be held for displayingpurposes. It being evident that by properly rotating the spindle G,motion may be imparted to the worm wheel, and thus the angle of the armJ may be varied, or said arm raised or lowered, or placed in horizontalposition as desired.

The screw or pin K forms the axis of the Wheel H, and serves to connectthe sections of the ear D. When said screw is removed, the sections ofthe ear may be separated,and the Worm wheel F,its spindle or shaft G,and the Worm wheel H with the arm J may be displaced from said ear. Theclip B may also be-unscrewed and removed from the standard A when sodesired.

The parts may be reassembled, the clip located, the screws tightened,and thus the device is again in operative condition.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A fixture arm havinga wheel connected with `the inner end thereof, incombination with ears connected with a clip, and formed in sectionshaving a chamber within the same, a worm mounted in said chamber meshingwith said wheel, and a pin on said ears supporting the Wheel, a sectionof the ear being pivotally mounted on said clip, and the parts namedcombined substantially as described.

2. The sectional ear D with the chamber E within the same, the worm Fmounted in said chamber, the worm wheel H engaging with said worm andthe pin K supporting said wheel and connecting the sections of the earD, in combination with the sectional clip B, said ear and clip havingknuckles, and an axial pin connecting the same, substantiall y asdescribed.

3. A clip formed in sections with knuckles thereon, and an axial pintleD2 connecting the same, the ear D formed in sections and IOO having a.knuckle connected by said pintle with the knuckles of the cli p, a. WormD within the sections of said earma Worm Wheel I-I mounted in said earmeshing with said worm, an arm J connected with said Worm wheel and theaxial pin K of the Wheel H, said pin K connecting the sections of theear D, said parte being combined substantially as described.

4. A support, a clip formed of pivoted sections zidjustabie on seidsupporta, an ear on said clip having a, section pivoted to said clip, :Lclamping pin for the sections of said ear, aworm Wheel mounted on saidclamping pin and having an arm projecting therefrom, I5 and a. Wormmounted in said ear between the sections thereof, said parts beingcombined substantially as described.
